context_page_description: The acacia ant is a species of ant of the genus Pseudomyrmex. These arboreal, wasp-like ants have an orange-brown body around 3 mm in length and very large eyes. The acacia ant is best known and named for living in symbiosis with the bullhorn acacia throughout Central America.
  The ant and the acacia exemplify a coevolution of a mutualistic system, as described by evolutionary ecologist Daniel Janzen.
context_section_description: P. ferruginea is an obligate plant ant that occupies at least five species of acacia (A. chiapensis, A. collinsii, A. cornigera, A. hindsii and A. sphaerocephala). Its life cycle conforms to the claustral pattern of ants in general.
